The Android operating system is used to control a digital camera. An Android camera not only has the higher-quality photography features seen in dedicated cameras, but it also runs the various Android apps available. An Android camera, often known as a "4G camera" or "connected camera," allows users to arrange images into folders and accepts image editing apps from the Google Play app store.
This tutorial shows you how to take a photo by outsourcing the task to another camera app on your device. (See Controlling the Camera if you'd rather develop your own camera functionality.) Assume you're building a crowd-sourced weather service that creates a worldwide weather map by combining images of the sky captured by smartphones running your client app.
Only a tiny portion of your application is comprised of photographs. You don't want to reinvent the camera; you just want to snap pictures with it. Fortunately, most Android smartphones come pre-installed with at least one camera app. You'll learn how to make it snap a photo for you in this session.
Your software has a task to complete, and video integration is only a small portion of that. You don't want to reinvent the camcorder, therefore you want to capture videos with as little effort as possible. Fortunately, most Android-powered smartphones already include a video-recording camera application.
Directly managing a device's camera necessitates a lot more code than just obtaining images or movies from current camera apps. If you want to create a specialist camera app or something that is entirely integrated into your app's UI, though.
Obtaining an instance of the Camera object is the first step towards manipulating the camera directly. The preferred approach to access the camera is to open Camera in a different thread that is launched from onCreate, like Android's native Camera application does ().
This is an excellent strategy because it can take a long time and bog down the UI thread. To ease code duplication and keep the flow of control simple, opening the camera can be delayed to the onResume() method in a more basic version.
On mobile devices, the Android framework supports a wide range of cameras and camera capabilities, allowing you to capture photos and videos in your apps. This paper covers an advanced strategy for developing bespoke camera experiences for your users, as well as a quick, easy approach to picture and video capturing.
